Best SD Card for Nikon Z6 II
The Nikon Z6 II is a versatile powerhouse, but its dual-slot design often leaves photographers scratching their heads over the SD slot. While the CFexpress slot handles the heavy lifting, your SD card needs enough speed to keep up with 14fps bursts and 4K/60p video. I’ve tested dozens of cards in my own Z6 II, and for most users, the SanDisk Extreme Pro UHS-II stands out as the most reliable workhorse to ensure you never miss a decisive moment.

Best SD Card for Nikon Z6 II: Detailed Reviews
SanDisk Extreme Pro UHS-II View on Amazon View on B&H
If you want a card that “just works” without ever worrying about the buffer choking during a wedding or a fast-paced sports event, the SanDisk Extreme Pro UHS-II is my top recommendation. With read speeds up to 300MB/s and write speeds of 260MB/s, it fully utilizes the Z6 II’s UHS-II secondary slot. I’ve found that when shooting in backup mode (writing to both cards simultaneously), this card keeps pace with the primary CFexpress card remarkably well. It’s V90 rated, meaning it handles 4K/60p video without a hiccup. The only real downside is the price premium over UHS-I cards, but for a 24.5MP sensor shooting at 14fps, that extra speed is a necessity rather than a luxury. It’s also shockproof and temperature-proof, which provides peace of mind when I’m out in the field during harsh winters.

Kingston Canvas React Plus View on Amazon View on B&H
The Kingston Canvas React Plus is the industry’s best-kept secret for the Nikon Z6 II. It offers V90 performance—the highest speed class for SD cards—at a price point that often beats out slower V60 cards from competitors. In my testing, the write speeds are consistently impressive, making it ideal for the Z6 II’s high-bitrate video modes. What really seals the deal for me is that Kingston includes a dedicated UHS-II USB reader in the box. If you don’t already have a high-speed reader, this saves you an extra $20-$30. While Kingston might not have the historical “pro photography” branding of SanDisk or Lexar, this card has proven incredibly stable in my workflow. The build quality feels standard, but the performance-to-price ratio is simply unbeatable for anyone who wants professional-grade speed without the inflated price tag.

SanDisk Extreme Pro UHS-I View on Amazon View on B&H
Not everyone shooting with a Nikon Z6 II is a sports photographer or a high-end videographer. If you mostly take family portraits, landscapes, or travel photos, the SanDisk Extreme Pro UHS-I is a fantastic way to save money. While it’s a UHS-I card and won’t hit the blistering speeds of its UHS-II siblings, it’s remarkably reliable. You’ll notice the camera’s buffer takes longer to clear after a burst, and you might be limited to 4K/30p for very long clips, but for standard 24MP stills, it’s more than sufficient. I often keep a few of these in my bag as emergency spares. They are incredibly affordable, meaning you can stock up on high-capacity 256GB or 512GB versions for long trips without breaking the bank. Just be aware of the “bottleneck” effect if you use it in backup mode alongside a fast CFexpress card.

Sony SF-G Tough Series View on Amazon View on B&H
For those who treat their gear like tools and not museum pieces, the Sony SF-G Tough is the ultimate SD card. This isn’t just about speed—though with 299MB/s write speeds, it’s arguably the fastest UHS-II card on the planet—it’s about the build. Sony removed the fragile plastic ribs and the tiny write-protect switch that always seems to break off on standard cards. It’s a solid piece of resin that is waterproof, dustproof, and virtually unbendable. I’ve used these cards in rainy forest shoots and dusty desert environments, and they never fail. For a Z6 II user who relies on the SD slot for critical backup, this is the safest “vault” for your data. It is significantly more expensive, but you’re paying for the peace of mind that your data is protected by the toughest shell in the industry.

Lexar Professional 2000x View on Amazon View on B&H
The Lexar Professional 2000x has been a staple in pro camera bags for years, and for good reason. It offers top-tier UHS-II performance that matches the Z6 II’s capabilities perfectly. While Lexar went through some corporate changes a few years ago, the 2000x series remains their flagship gold standard. In real-world use, the read speeds make transferring 128GB of photos to my computer a breeze, which is a lifesaver after a long day of shooting. It’s V90 rated, so it’s fully compatible with all of the Z6 II’s video modes, including the demanding ProRes RAW external output or high-frame-rate internal recording. It’s a very balanced card that offers great speed and decent durability, though I still prefer the Sony Tough for pure physical resilience. It’s a solid alternative if SanDisk is out of stock.

Frequently Asked Questions
Does the Nikon Z6 II need a UHS-II card?
Technically, no. The Z6 II is backward compatible with UHS-I cards. However, using a UHS-I card will significantly slow down your buffer clearing speeds and may prevent you from recording the highest quality 4K video. If you use the SD slot as a backup to the CFexpress slot, a slow card will bottleneck your entire camera. I highly recommend UHS-II for the best experience.
Can I use two SD cards in the Nikon Z6 II?
No, the Z6 II features two different types of slots. Slot 1 is designed for CFexpress Type B or XQD cards, which are much faster and physically larger. Slot 2 is designed specifically for SD cards (UHS-II compatible). You must have one of each if you want to use both slots simultaneously for backup or overflow storage.
What is the best card for 4K 60p video?
For 4K 60p video on the Z6 II, you should look for an SD card with at least a V60 rating, though a V90 card is preferred for total reliability. V90 cards like the Kingston Canvas React Plus or the SanDisk Extreme Pro UHS-II guarantee that the write speed never drops below 90MB/s, which is crucial for high-bitrate video recording without dropped frames.
Is CFexpress better than SD for the Z6 II?
Yes, CFexpress Type B cards are significantly faster than even the best SD cards. They allow for virtually unlimited burst shooting and much faster offloading to your computer. However, the SD slot is vital for providing a real-time backup of your work. Most pros shoot to both simultaneously, so having a high-quality SD card is just as important as the CFexpress card.
How many photos can a 128GB SD card hold?
On a Nikon Z6 II, a 128GB card will typically hold around 3,200 Lossless Compressed 14-bit RAW files. if you shoot JPEG Fine, you can expect upwards of 10,000 images. For video, 128GB will give you roughly 40-50 minutes of 4K 60p footage depending on your bitrate settings. For most users, 128GB is the perfect balance between cost and capacity.
Final Verdict
For the professional photographer using the Nikon Z6 II, I cannot recommend the SanDisk Extreme Pro UHS-II highly enough—it’s the card I personally trust for my paid gigs. However, if you’re looking to maximize your budget without sacrificing speed, the Kingston Canvas React Plus is a phenomenal alternative that even includes a free reader. Choose the Sony Tough if you’re an adventurer, but for everyone else, these top three will keep your Z6 II running at peak performance.
